1 Claim.

The invention relates to new and useful improvements in containers, and more particularly to a friction closure for containers.

An object of the invention is to provide a container having a friction seat for a closure, which friction seat makes extended contact with the closure in a direction lengthwise of the container.

A further object of the invention is to provide a friction seat for a closure for a container of the above type wherein said friction seat is supported at one end and reinforced and strengthened by a false wiring at the other end thereof.

In the drawing: r

Figure 1 is a perspective view of a container having my improved friction closure applied thereto.

Fig. 2 is a sectional view on the line 2-2 of Fig. l.

The invention is shown as applied to a container which is cylindrical and which consists of a body portion having a top double-seamed thereto. The top has an opening therethrough and the metal forming the top is shaped at the opening so as to provide a friction seat for a closure. The metal is preferably bent upwardly and then downwardly to form an extended friction seat for the closure. The extreme lower portion of the downwardly bent metal is rolled into a false wire which strengthens and reinforces the wall forming the friction seat, and at the same time said false wire permits a certain amount of yielding action without fracturing the metal so that thefriction seat will accommodate itself to the friction wall on the closure.

The closure consists of a cup-shaped member having an extended wall which engages the friction seat on the top. The extreme upper portion of the closure is flanged and turned underneath the flange so as to reinforce said closure to aid in the support of the friction wall formed therein and also to aid in the removal of the closure.

Referring more in detail to the drawing, the container to which the invention is applied consists of a cylindrical body portion 1 having ears, one of which is shown at 2, to which a bail 3 may be attached. The body portion is provided with the usual bottom and is also provided with a top 4 which is joined to the wall of the body portion by a double seam 5. The top 4 has an opening centrally thereof and the metal adjacent the opening is bent upwardly at 6 and thence downwardly at 7, thus forming an extended friction seat for the closure. The extreme lower portion of the wall forming the friction seat is rolled outwardly and upwardly into a false wire 8. This upward bending of the metal as at 6 and the rolling of the lower part of the metal into a false wire provides an extended friction seat or wall which is strengthened both by the bending of the metal at the top and the rolling of the metal at the lower edge portion thereof.

This rolling of the metal at the lower portion of the wall '7 also places the raw edge of metal so that there is no possible chance of the hand of one reaching into the container contacting with said raw edge. The rolling of the lower portion of the wall into a false wire not only reinforces said lower edge portion, but at the 7 same time, it gives a certain elasticity thereto, as pressure applied against the wall adjacent the lower edge thereof would tend to roll the edge portion further rather than to split the edge portion.

The opening in the top 4 is adapted to receive a closure 9. This closure 9 is cup-shaped, thus providing an extended wall 10 which is the frictional wall that contacts with the friction seat on the top 4. The upper portion of the closure is bent or flanged outwardly as indicated at 11 and is then bent underneath so that the upper edge of the closure is strengthened and reinforced. Furthermore, this flange extends outwardly so as to overhang the inclined portion 6 of the top and this enables an instrument to be readily inserted beneath the flange 11 for the prying out of the closure 9.

It will be noted from the drawing that the friction seat has an extended surface contact with the wall on the closure and the lower portion of the wall on the top will yield, as above noted, so that there is a metal to metal contact between the wall or seat on the top and the wall on the closure throughout substantially the entire height of the friction seat on the top.

The false wire does not make contact with the wall 7 at its free edge; neither is the false wire rolled into a solid roll; it is an open roll and this permits the lower edge portion of the friction seat to yield, as stated above. I

It will be obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1' o A metal container comprising a body portion, 1

a top secured thereto, said top having an opening centrally thereof, the metal of the top adjacent said opening being bent upwardly, thence downwardly to substantially an equal distance below the metal of the top to provide an extended vertical friction wall seat for a friction top closure,

the lower edge portion of said wall being rolled outwardly and thence upwardly to form a hollow
